Description

Technical Field

[0001] The utility model relates to the technical field of crucible molds, in particular to a safety protection device for a crucible extrusion mold. Background Art

[0002] Molds are various molds and tools used in industrial production to produce desired products through methods such as blow molding, injection molding, extrusion, forging, and smelting. Simply put, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. Quartz crucibles are consumables in the polysilicon ingot casting process. With the explosive growth of the photovoltaic market, the demand for crucibles is increasing, and the crucible size is also increasing. The manufacture of quartz crucibles requires the use of crucible mold safety devices.

[0003] However, the safety protection device for the crucible extrusion mold in the prior art is relatively simple, and the specific temperature of the crucible cannot be known during the cooling stage after the crucible is extruded. The workers may be burned during the demoulding process. At the same time, it cannot protect the workers from being burned when the crucible is heated due to the rapid boiling of the material due to splashing. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a safety protection device for a crucible extrusion mold, characterized in that it includes: a base, the surface of the base is provided with four threaded holes 1 and four threaded holes 2, the internal threads of the four threaded holes 1 are connected with four bolts 2, the internal threads of the four threaded holes 2 are connected with four bolts 1, the surfaces of the four bolts 1 and the four bolts 2 are provided with anti-splash injury components, the top of the base is fixedly connected with a bottom plate, the bottom of the inner cavity of the bottom plate is provided with three installation grooves, and the interiors of the three installation grooves are provided with temperature prompt components.

[0006] As a preferred embodiment, an L-shaped support arm is fixedly connected to the surface of the base, a cylinder is fixedly connected to the bottom of one side of the L-shaped support arm, and a die is fixedly connected to the bottom of the cylinder.

[0007] The two wheels are fixed together by a toothed plate, and the two wheels are connected with each other through a hole, and the two wheels are connected with a toothed plate at the bottom.

[0008] As a preferred embodiment, the temperature prompt component includes a control terminal, a red prompt light, a green prompt light and three temperature sensors, and the tops of the three temperature sensors are fixedly connected to a heat conducting plate.

[0009] As a preferred embodiment, the surfaces of the four first bolts are movably embedded in the four first through holes, and the surfaces of the four second bolts are movably embedded in the four second through holes.

[0010] As a preferred embodiment, one side of the control terminal, the red indicator light and the green indicator light are fixedly connected to one side of the isolation box, the bottoms of the three temperature sensors are fixedly connected to the bottoms of the inner cavities of the three mounting grooves, and the surfaces of the three heat conduction plates are fixedly embedded in the interior of the three mounting grooves.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the present invention, the crucible mold material is first heat-treated before extrusion molding to increase its own plasticity for extrusion molding, and then the mold material after heat treatment is placed in the base plate for extrusion molding. Before starting the crucible extrusion mold, the staff controls the control terminal to start the bidirectional motor. The output end of the bidirectional motor drives the gear to rotate, and the gear is engaged with the rack to drive the isolation box to move, and it moves until one side of the inner cavity of the isolation box contacts the surface of the baffle, so that the crucible extrusion mold device is completely isolated on the inner side of the anti-splash injury component. After the above protective measures are implemented, the cylinder is started to drive the die to press down for molding. This design prevents the material inside the base plate from splashing out during the molding process and injuring the surrounding staff.

[0013] 2. According to the utility model, after the crucible extrusion mold device completes the molding, the staff controls the control terminal to reversely start the bidirectional motor, opens the anti-splash injury component, and accelerates the heat dissipation of the material in the bottom plate. The three temperature sensors will detect the crucible mold extruded in the bottom plate in real time, transmit the detected temperature information to the control terminal, and display the real-time temperature through the display screen on the control terminal. The normal temperature limit value is set by the control terminal. When the temperatures detected by the three temperature sensors are all lower than the set value, it is considered to have reached normal temperature, and the green prompt light is on. When the temperatures of the three temperature sensors are higher than or have exceeded the set value, the red prompt light is on. In this way, after the molding is completed, the temperature of the material in the bottom plate and the auxiliary prompt indicator light can be understood in real time to remind the staff, so as to prevent the staff from being unaware or not paying attention and being scalded during the demolding work.
